Interior layered deposits within an embayment in the northern as well as near the
southern wall of Coprates Chasma in the Valles Marineris, Mars are studied using HRSC,
CTX, HiRISE and CRISM data. In the northern ...

The inverse relationship between arboreal lichen species richness and sulphur
dioxide in ambient air has been thoroughly documented in the literature. Previous
work in southern Ontario has shown that lichen bioindication ...

Micromorphology is used to analyze a wide range of sediments. Many microstructures have, as yet, not been analyzed. Rotation structures are the least understood of microstructures: their origin and development forms the ...

High chromium content in kimberlite indicator minerals such as pyrope garnet
and diopside is often correlated with the presence of diamonds. In this study, kimberlite
indicator minerals were examined using visible light ...

Marine palynology and benthic and planktonic foraminiferal geochemistry are combined
to reveal long- and short-term (Milankovitch-scale) paleoceanographic changes across
the upper half of the Olduvai Subchron (ca. ...

Crawford Lake, Ontario, provides an ideal natural laboratory to study the response of freshwater dinoflagellates to cultural eutrophication. The anoxic bottom waters that result from meromixis in this small (2.4 ha) but ...

Sediments recovered from seven Last Glacial Maximum grounding lines sites, around
the Antarctic Peninsula, were analyzed using micromorphology. This is the first
evidence that grounding line sediments from around the ...

On Mars, interior layered deposits (ILD) provide evidence that water was once
stable at the surface of the planet and present in large quantities. In West Candor
Chasma, the ILD and their associated landforms record the ...
